Ozone day

September 16 was designated by the United Nations General Assembly as the international day for the Preservation of the Ozone Layer. This designation had been made on December 19, 2000, in commemoration of the date, in 1987, on which nations signed on the Montreal Protocol Substances that Deplete the Ozone Layer. In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.

The closure of the hole in the ozone layer was observed 30 years after the protocol was signed. Due to the nature of the gases responsible for ozone depletion their chemical effects are expected to continue for between 50 to 100 years.

"Caring for all life under the sun"

This year marks the 30th anniversary of the Montreal Protocol. As part of the anniversary celebrations, the Ozone Secretariat will launch a communication campaign ahead of World Ozone Day to be marked on 16 September 2017.

The OzoneHeroes campaign to be launched on 14 September will seek to celebrate the major accomplishments of the Montreal Protocol in protecting the ozone layer and the climate, to increase public recognition of the success and impact of the Protocol, and to generate further support for the Protocol and its new mandate to phase down climate-warming hydrofluorocarbons under the Kigali Amendment, adopted in 2016.
